Final answer:
The statement not true about bacteria is that they contain membrane bound organelles; bacteria are prokaryotic and do not possess these structures.
Step-by-step explanation:
The statement that is NOT true about bacteria is: A. Bacteria contain membrane bound organelles. Bacteria, being prokaryotic cells, lack nuclei and other membrane-bound organelles such as mitochondria and chloroplasts. Instead, they have a cell wall composed of peptidoglycan, which provides structure and protection. Some bacteria are capable of photosynthesis, have flagella for movement, and are indeed all prokaryotes as stated in the options B, C, and D, respectively. The correct answer, A, indicates a feature of eukaryotic cells, not prokaryotic bacteria.
